Solution Overview

Problem

Existing ballistic armor systems are either heavy and inflexible, uncomfortable to use, and unable to effectively deflect high-velocity projectiles at varying angles of incidence, or they fail to optimize protective coverage while minimizing areal density, with current flexible body armor systems being criticized for insufficient bonding and edge threat defeat capabilities.

Innovation Solution

A flexible ballistic armor apparatus comprising multiple spherical units made of fragmentation materials, such as tempered amorphous silica or ceramic, coated with ceramic materials, arranged within an inner and outer envelope of non-ballistic and fibrous fabrics, respectively, to dissipate kinetic energy and redirect projectile force vectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If large rigid ceramic plates are used as shields, then threat defeating capability is improved, but weight and flexibility increase making them uncomfortable to use

Engineering Contradiction:
Improvethreat defeating capabilityVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The armor system divides the protective function into multiple components: flexible fabric layers for base protection and separate ceramic disk inserts for enhanced threat defeat. This segmentation allows the user to carry only the necessary protection level and enables the flexible armor to conform to body contours, reducing effective weight burden.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs flexible fabric carriers and thin ceramic disks instead of large rigid plates. The flexible fabric allows the armor to conform to body shapes and move with the wearer, while thin ceramic inserts provide targeted protection against projectiles. This combination maintains threat defeating capability while dramatically reducing weight and improving comfort.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If soft fabric ballistic resistant materials are used, then flexibility and comfort are improved, but ability to deflect high-velocity projectiles at varying angles deteriorates

Engineering Contradiction:
ImproveflexibilityVSAvoidprojectile deflection capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent merges two complementary protection mechanisms: soft fabric ballistic resistant materials that provide flexibility and comfort, combined with ceramic disk inserts that excel at deflecting high-velocity projectiles at varying angles. The ceramic disks' hardness and geometry provide superior projectile deflection, while the flexible fabric carrier maintains comfort and conformability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The armor system uses composite construction combining organic fabric materials with inorganic ceramic materials. The fabric provides flexibility, comfort, and basic ballistic resistance, while the ceramic inserts add hardness for high-velocity projectile deflection. This composite approach achieves both flexibility and reliable projectile deflection across varying angles.

Inventive Principle:
Principle #40Composite materials

3Strength

If ceramic disks are overlapped to spread force, then penetration resistance is improved, but bonding sufficiency and edge threat defeat capability deteriorate

Engineering Contradiction:
Improvepenetration resistanceVSAvoidbonding sufficiency
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent incorporates edge extensions on the ceramic disks that protrude beyond the fabric carrier boundaries. These edge extensions are designed in advance to provide threat defeat capability at the edges of the armor unit, addressing the weakness of conventional bonded ceramic systems before edge attacks occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The ceramic disks are curved to conform to the body's contour, creating a spherical or curved surface geometry. This curvature allows the disks to maintain contact with the body and each other, improving force distribution and maintaining protection effectiveness at edges and corners where flat plates would be vulnerable.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Reliability

If armor coverage is increased to optimize protection, then protective capability is improved, but areal density increases

Engineering Contradiction:
Improveprotective coverageVSAvoidareal density
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The armor system divides protection into modular ceramic disk inserts that can be selectively placed on the fabric carrier. Users can configure the number and distribution of ceramic disks based on specific threat levels and protection needs, optimizing protective coverage without unnecessarily increasing areal density in low-threat areas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies ceramic disk inserts selectively to areas requiring enhanced protection while leaving other areas with only fabric protection. This local quality approach concentrates areal density where it is most needed for threat defeat while maintaining overall flexibility and comfort in less critical areas.

Inventive Principle:
Principle #3Local quality
